The Land Use/Land Cover Change for Nearly 20 Years and Their Impaction Landscape Patterns:Taking Beibei District for Instance

Based on the landscape pattern index,the spatial pattern analysis is currently an important basis for the content of the Landscape Ecology.Land-use type significantly affects the landscpe pattern index.Using the TM image in 1988 and the CBERS(CBERS-02)image,combined with the RS and GIS technology,we studied the land use/cover change and its impact on the lancscape pattern analysis for the past 20 years in Beibei District and found the trend of land-use/cover changes are the area of cultivated land and other land uses tending to decrease;The residential land、industrial as well as mining as,forest,waters and water conservancy facilities land tending to increase;Reading the landscape shape index,we can see housing,industrial and mining sites and other sites tending to complex shapes;Woodland,arable land and water,due to human intervention tending to simple.From the landscape fractal dimension and the fragmentation of view,we can see the number of fractal dimension of the housing,industrial and mining land use and other building land increased,and other types of fractal dimension decreased.The region,for construction should be strictly controlled to enhance ecological planning and earnestly protect arable land.
